There were a couple things I was wondering as I watching past episodes.  I was hoping some of you had answers or explanations.  I know a lot of you might say things like "Heller sucks" or "they just have plots holes that don't make sense."  But I wanted real explanations about a couple of things.  
So Red John was always impossible to identity or capture.  A lot of people who knew him died before they ever provided information as well.  Patrick even says: "People who can identify Red John end up dead."  There are two specific instances I want to bring into question.
1) In "His Red Right Hand" (2X08) Rebecca Anderson is poisoned and dies.  She falls seconds after RJ (or someone he sent) walks by.  How come the two people who were escorting Rebecca weren't questioned about what the man looked like?  If it was Mcallister, wasn't it weird to them a sheriff is walking by himself in that hall?

2)  In "Red Blinking Light" (4X07) Jane gets Panzer to talk negatively about Red John.  Later, Red John kills Panzer.  This was all part of Jane's plan.  I know Red John is tricky and everything like that, but how come Jane doesn't spy on Panzer so he can at least pick up a clue when RJ comes to kill him? Granted, Jane probably wouldn't have been able to catch/kill RJ, but he knew it was a good possibility that RJ would go kill Panzer!  I remember someone saying this is one reason they thought PJ was in fact RJ.  Why does Patrick just sit and wait?  Maybe set up a trap or something so he can get new info on Red John in that case. 

Ok, so a lot of clues weren't explained such as, "He is Mar", Visualize connection, how RJ got the list, etc etc etc but I've also wondered about RJ and his followers.  The blake association doesn't explain why people would die for him.  I was hoping during the Red John reveal we would understand how he got people like Lorelei and others to do everything he asked of them.
